No functional changes, just a refactoring.
Use more specific and meaningful names to be able to use these errors from external packages.

During new transaction verification if there's an on-chain conflicting
transaction, we should check the signers of this conflicting transaction.
If the signers intersect with signers of the incoming transaction, then
the conflict is treated as valid and verification for new incoming
transaction should fail. Otherwise, the conflict is treated as the
malicious attack attempt and will not be taken into account;
verification for the new incoming transaction should continue.
This commint implements the scheme described at
https://github.com/neo-project/neo/pull/2818#issuecomment-1632972055,

Witnesses are not yet created by the moment we return this error,
thus, it was always 0 as an actual number of witnesses in
ErrInvalidWitnessNum.

`(*Blockchain).HasTransaction` is one of the oldest methods in our
codebase, and currently it's completely unused. I also doubt that
this method works as expected because it returns `true` if transaction
in the mempool.

Ensure that Scopes can be properly parsed not only from the string
representation, but also from a single byte. transaction.Signer
is not affected (checked against the C# implementation), only
RPC-related signer scopes are allowed to be unmarshalled from byte.

This check is good and was present here since #1729, but it was
accidently removed from the reference implementation (see the
discussion in https://github.com/neo-project/neo/issues/2848). The
removal of this check from the C# node leaded to the T5 testnet state
diff since 1670095 heigh which causes inability to process new blocks
since 2272533 height (see #3049). This check was added back to the
C# node in https://github.com/neo-project/neo/pull/2849, but it is
planned to be the part of the upcoming 3.6.0 C# node release.
We need to keep our testnet healthy, thus, strict contract script
check will be temporary removed from the node code and is planned
to be added back to be a part of the next 3.6.0-compatible release.
Close#3049.

Our wrapping optimization relied on the caller context having a TRY block,
but each context (including internal calls!) has an exception handling stack
of its own, which means that for an invocation stack of
entry
A.someMethodFromEntry() # this one has a TRY
A.internalMethodViaCALL() # this one doesn't
B.someMethod()
we get `HasTryBlock() == false` for `A.internalMethodViaCALL()` context, which
leads to missing wrapper and missing rollbacks if B is to THROW. What this
patch does instead is it checks for any context within contract boundaries.
Fixes#3045.

That's the way how C# node handles equality checks for stackitem.Interop types
for these points. Ref. https://github.com/nspcc-dev/neo-go/issues/3002#issuecomment-1591220501.
Along the way, add GT case for CryptoLib's bls12381Equal method. It should be there since #2940.

If the contract was deployed then cache must be initialized after
in-memory data reset. If the contract isn't active yet, then no
cache will be initialized on deploy (i.e. on call to Initialize()
method by native Management).

Make the contracts cache initialization unified. The order of cache
iniitialization is not important and Nottary contract is added to the
bc.contracts.Contracts wrt P2PSigExtensions setting, thus no functional
changes, just refactoring for future applications.

I've carefully checked the way how new service can be added to the
Blockchain instance or to be removed from it. Current implemention
of SetNotary and SetOracle methods doesn't contain dangerous code,
and native contracts have atomic values everywhere where service
is stored.
Current implementation of Notary, Oracle and StateRoot services'
reload/disabling/enabling on SIGUSR1 is safe and doesn't require
any adjustment.
This commit closes#2944, it's not a bug in the code, it's just
stale documentation.

`cache` persisting operation is concurrent with the storage modifications
made by further state reset stages. We can't allow situation when data
from the next stage are leaking into the previous stage. State reset stages
must be atomic in turms of DB persisting, thus, use another `upperCache`
MemCached store to keep them apart.
